You'll need to list a few more details, such as:
- your investment options - every plan is different, and there's no way any of us can guess what options you might have
- what do you mean by "risk averse"? Are you worried about panic selling?
- Why do you want dividends? Especially in a retirement account, you really shouldn't care what form your returns take, you should only care about total returns.
- When do you expect to retire?
- Do you have any other investments?
You can also always change your investments later, there's no tax penalty or other costs within a 401k for selling and buying.
The Lifepath 2050 seems like a decent option. I did a little research, and the Lifepath 2040 has 25% bonds, whereas the 2050 is ~8% bonds, so it'll be getting quite a bit more conservative over the next 10 years. 25% bonds is a little high for someone just starting out and a little low for a retiree, so I'd really need to know what your retirement horizon looks like to know what would make sense for you.
